FEATURES

• Four independent, full duplex DS1 Tx and Rx Framer/LIUs

• Two 512-bit (two-frame) elastic store, PCM frame slip buffers (FIFO) on TX and Rx provide up to 8.192 MHz

asynchronous back plane connections with jitter and wander attenuation

• Supports input PCM and signaling data at 1.544, 2.048, 4.096 and 8.192 Mbits. Also supports 4-channel

multiplexed 12.352/16.384 (HMVIP/H.100) Mbit/s on the back plane bus

• Programmable output clocks for Fractional T1/E1/J1

• Supports Channel Associated Signaling (CAS)

• Supports Common Channel Signalling (CCS)

• Supports ISDN Primary Rate Interface (ISDN PRI) signaling

• Extracts and inserts robbed bit signaling (RBS)

• 3 Integrated HDLC controllers per channel for transmit and receive, each controller having two 96-byte

buffers (buffer 0 / buffer 1)

• HDLC Controllers Support SS7

• Timeslot assignable HDLC

• V5.1 or V5.2 Interface

• Automatic Performance Report Generation (PMON Status) can be inserted into the transmit LAPD interface

every 1 second or for a single transmission

• Alarm Indication Signal with Customer Installation signature (AIS-CI)

• Remote Alarm Indication with Customer Installation (RAI-CI)

• Gapped Clock interface mode for Transmit and Receive.
